What you want is not possible because DNS resolves to one IP, not to a NAT’ed
Doing this differently is very hacky and totally unsupported. One host, one IP,
one DNS record. NAT doesn’t belong in this type of networking.
If you really wanted to shoot yourself in the foot, you can use Unbound and a
Python plugin to do record-rewriting on the fly. The IPA DNS server would
return 10.3.2.33 for example and that would be rewritten to 172.16.2.33 if you
Queries would have to go to the unbound server and it forwards them to the IPA
server. Responses are then rewritten on the fly if they contain the foreign IP
range. This is bad in so many ways…
